Brazil's B3 Exchange is set to launch six new derivatives contracts on April 27, allowing high-net-worth investors to speculate on future events, including Bitcoin prices. These Event Contracts, similar to prediction markets like Kalshi and Polymarket, are priced up to 100 reals ($19) and reflect market probabilities. Regulated by Brazil's CVM, these contracts are designed for professional investors with assets exceeding 10 million reals ($1.9 million) or CVM certification. The contracts cover mini futures and spot prices for the Ibovespa index, U.S. dollar, and Bitcoin, with cash-based settlements. B3's vice president, Luiz Masagão, highlighted the launch as part of efforts to modernize Brazil's derivatives trading. This marks Brazil's first federally regulated prediction market, entering a competitive field with platforms like Prévias and Palpitada. The global prediction market is booming, with notional volume nearing $160 billion and major players like Polymarket and Kalshi leading the space. However, regulatory clarity remains a challenge in Brazil, with debates on whether oversight should fall under the CVM, Central Bank, or Ministry of Finance.
